    For this follow steps below
    1. create a function BindGrid with input param tableName as string
    2. In function BindGrid create a SqlDataAdapter with sql query "Select * from "+ tableName +""
    3. Create a DataTable object and fill it with SqlDataAdapater
    4. Pass it as DataSource to DataGrid
    5. On SelectedIndexChange of DropDownList call function BindGrid and pass DropDownList.SelectedItem as param into it
